Strategy Tips for Limited Stage 15
Take Advantage of Stage Effects

In "Signal of Disruption," stage effects will activate. These effects synergize well with Reno Ichikawa and Sagan Shinomiya, so it's recommended to use the 5-Star versions of Reno and Sagan to clear the stage.
Reduce Enemy Plates Efficiently
In "Signal of Disruption" Fierce Battle Area Limited Stage 15, the enemy's Plates are Shot and Physical in the first half, and Blunt, Shot, Physical, and Elemental in the second half. Reduce each Plate efficiently to trigger Core Exposed and gain an advantage in battle.
Try to Level Characters to 100

During battle, if your characters are lower level than the enemies, you will take more damage, making it harder to achieve the "Win with 0 incapacitated units" star condition. In Limited Stage 15, enemies are level 90 with high HP, so it's recommended to challenge them with your characters at Lv. 100 to increase your damage output.
